All three maps analyze the number of mobile phone subscribers in each
country.
Dot Density Map
The number of dots in each country represents the density of
mobile phone subscribers. Countries like Colombia and Ecuador have a
higher density of mobile phones subscribers, represented by the denser
cluster of red dots in those countries. Countries like Guyana, Suriname,
or Uruguay, which have a noticeably smaller concentration of dots.
Proportional Symbols Map
The size of the dot on each country represents the number of
mobile phone subscribers. Brazil has the largest dot on this map,
highlighting that they have the highest amount of mobile phone
subscribers out of all the South American countries shown. One thing to
note is that while Brazil has the largest number of subscribers, it does
not have the highest density of subscribers as we already established
with our DDM that Colombia has the highest density.
